Then, it...

Calibration of Laser Tracker systems is based most times in the determination its geometrical errors. Some standards as ASME B89.4.19 (2006) and VDI 2617-10 (2011) describe different tests to calculate geometric misalignments that cause systematic errors measurements. These are caused not only because other sources error must also be taken count. In this work we want express a kinematic form. Errors will split two components, The first ones depend on offsets, tilts eccentricity mechanical...
